Specification of letcez's'Patent.

Patented July 12, 1910.

Application filed March 16v 1907. Serial No. 362,753.

To all zr/iom it may concern:

Be it known that l. .\RTHL'R J. Batons, citizen of the l nitcd States.and resident of Syracuse. in the county of )nondaga and State of NewYork, have invented certain new and useful Improvements in Typo \VritingMachines, ot which the following is a specification.

My invention relates especially to billing devices for typevvritin;machines and has for its" principal object to provide improved devicesof the character specified.

Another object of the. in vcntion is to provide improved automatic paperstop mechanism.

Another object is to provide an improved automatic paper clampingmechanism.

Another object is to provide improved line spacing devices.

To the above and other ends my invention consists in the features ofconstruction, com; bination's of devices and arrangen'ients of partshereinafter described and particularly pointed out in the claims.

My invention is shown as applied to a Smith Premier typea'ritingmachine, but. it is to be understood that said invention may be adaptedto other forms of writing machines.

In carrying out the invention in the pres ent instance a platen havingtwo axle sections is employed. one. of said. axle sections beingmaintained in a fixed relation with the platen and the other axlesection being rotatable rclativel to the platen. The platen carries aplurality or set of independently movable springprcssed members whichcombine the functions of sto s for that edge of the paper or work sheettii'st introduced into the machine. and of clamps for said work sheet.The. stop and clamp members are actuated b'y cams arranged on therelatively rotatable axle section and said axle section may be rotatedby means of a pinion fixed thereto and a cooperating handcontrollcd gearsegment pivoted on the platen carrier, said hand-controlled segmentbeing in the nature of a. supplementary line spacing lever. Connectionbetween the platen and the relatively rotative axle section is madethrough a ratchet and pawl mechanism. the ratchet being fixed to saidaxle section and the pawl to the platen head. the result. being, thatthe hand-operated gear segment serves as a line spacin" lever and in thecourse of lined I am enabled to automatieall open the stop and clampmembers to receive the bill 01 work sheet at a predetermined point.

' in the rotation of the platen, after which the Supplementary linespacing lever or handt'ontrolled gear segment is operated to clamp thebill by means of said clamping members and to turn or sweep the platento a position for receiving the first line of writing on the bill. Thesubsequent turning movements of the platen to space between the lines ofwriting are preferably obtained by operating the usual line spacinglever, causing the usual line spacing pawl to cooperate with the crownratchet teeth on the platen head. After the completion of the bill thesupplementar line spacing lever may be operated to rapidly rotate theplaten to the initial position, the combined clamp and stop membersbeing automaticall actuated so that the written bill is released andsaid members are properlv. positioned to cooperate with the next bill orwork sheet as it is introduced into the machine.

My improvements and their modeof operation will be better understoodfrom the more extended description and explanation to follow.

In the accom anvin drawin s. Fi ure 1' -b t h is a right-hand sideelevation of the upper part of a Smith Premier typewriter machine towhich myinvention is shown as applied, the right-hand platen fingerwheel being sectioned away. Fig. 2 is a longitudinal central sectionalview of the platen showing the mounting of the latter and variouscooperating devices. Fig. 3 is an enlarged fragmentary plan view showingpart of the platen and one of the combined clamping stop members. Fig. 4is a fragmentary plan view showing the latch, the main feed roller andthe combine clam Jing and stop members. Fig.5isa right-ban end view ofthe platen showing the platen head partly broken away to expose theinterior of the. platen, other parts bein shown in section and thesupplementary line spacing lever being shown in dotted lines. This viewshows the platen in what may be termed its initial position or thatposition in which the hill .or work sheet is int-reduced into the sideplates numhercd resptmtively l8 and 19. Z said side plates hem;connected by a front machine. Figs. t3 and T are views similar to Fig.5, hut showing some of the parts in ditlerent relations from those inwhich they l bar 20 and a rear har ll.

appear in said Fi .5, other parts shown in i the latter figure be ingomitted. Figs. 5 and 9 show respectively a right hand end view of theplaten and a fragmentary corresponding rear view of the platen and theregular line spacing-pawl. Figs. 10 and 1:: show views similar to Fig.8, the parts being shown in dillerent stages of operation from 1 thosein which the Y appear in said 1 1g. 5, 5

whereas Figs. 11 and 13 show views similar to Fig. 9 but show tlh: partsas they appear at (litter-ear stages of the operation. Figs. M and 15are views resembling Fig. 5, but showing the parts in diti'erentrelations from those in which they appear in the first named figure.Figs. 1t and 1T are also views resembling Fig. 5 but showing still otherstages in the operation of the parts.

Referring first more especially to Figs. 1 and 2, the main frame of themachine comprises corner posts 1 sustaining a top plate 2 on which areoppositely disposed front and rear grooved track-ways numberedrespectively 3 and 4. These track-ways rece'ive anti-friction balls 5which also co-l operate with the grooved front bar (3 and l rear barcomprising side or end hars t of a carriage truck, the latter also i Aplaten f section having a hearing on each of the platen heads 1:! and123. The axle sections are journaled on a platen frame or carrier whichcomprises left and right-hand end or tuds 2'2 project laterally outwardfrom the end plates of 5 the platen frame and are engaged lay hookedlinks 2-! pivoted at ll to the carri.-ige truck. it will he understoodthat the platen carriage comprises the truck and the platen frame orcarrier, and that the latter. together with the platen. is adapted to hero ked on the truck to expose the writing It will further he understoodthat the platen carriage is connected with the. usual sprine:

dram mechanism and is controlled by the 1 l l a l comprising the usualwooden core 9 and external sheath 10 of rubber or the like has P securedto its ends by the usual wood screws 11 platen heads 12 and 13, theleft-hand platen head 12 being provided with an elongated hub or boss 1-The platen axle in the present case preferably is composed of twosections, a comparatively short left-hand section 15, the inner end ofwhich terminates within the hub 14 of the left-hand platen head, theaxle section 15 being fixed to the hub by a screw 16 and consequentlybeing at all times maintained in a fixed relation with the platen. Theouter end of the axle seetion 15 hears on and projects beyond thelefthand side bar 8 of the carriage truck and is provided with a fingerwheel (not shown) through which the platen may be rotated in linespacing direction at will. The other axle section 17 ahuts at its leftend the shorter section 17) and extends through the platen from left toright, passing through the right-hand platen head 13 and having abearing on the right-hand side bar 8 of the carriage truck. The outerend portion of the axle section 17 may carry a finger wheel of the usualconstruction. The axle section 17 is not fixed to the platen. so thatrelative turning movements between the section 17 and the platen may beeffected, the

usual escapenient devices that at each printing operation the platen andplaten carriage may be drawn a letter space disa-ice htward a 'ross thetop plate on the ark-ways 31 and 4; under the influence of the springdrum mechanism. The rear hat or rod 2! of the platen carrienfixedlysupports upwardly extending standards or arms J5 to which is suitablysecured a paper. table it; of theusual construction. Links 2? (Fig.

1) are pivoted to and depend from the rear har or rod 21. said linkscarrying a rod or shaft E23 (Fig. -i) on which is mounted a main feedroller comprising, in the present instance. a metal core 29 rotatable onthe rod or shaft 28. said core carrying a plurality of feed rollsections 30 of ruhher or the like. The links .2? at their lower endscarry a rod 31 (Fig. 1) which pivotally supports a paper plate 32 of theusual construction, the latter l eiug held in contact with the platen orthe paper thereon by the lower rear end portions of paper lingers 33which are secured to sliding arms ll mounted on the front bar or rod .50of the platen carrier. The main feed roller is normally maintained incontact with the platen or the paper thereon by the usual or suitahleleaf springs 30.

The paper feeding and controlling devic s Referring now to the novelstop and' clamp members and their mounting. the sheath it) of the platenis flattened substantially throughout its length as indicated at inFigs. 2 and 3 and in arious of the operatin; views. l-loles are ormed inthe platen through the tlattened portion 35. these holes receivingcup-like casings or housings 36 which are provided with elliptiealflanges 37. the latter heiug received in countersinks in the flattenedportion 35. so that the outer faces of the flanges are flush with thesurface of the flattened portion.

platen will now be described.

Each housing or casing 36 is secured to the platen by wood screws 38which pass through the flanges 37, one at each side of the body of thehousing. the flanges being countersunk to receive the heads of saidscrews which are flu h with the outer faces of the flanges. The interiorof each housing is bored out, a indicated at 39 (Fig. 2) and receives aplunger-like clamping and stop member comprising a stem 40. a head 11and an angularly disposed flattened clamping lip 4:2 beveled on itsouter face from the free end of the lip to the end thereof whi aconnects with the stem 40 as shown'in Fig. 15 for instance. The clampinglip 42 is arranged exteriorly of the. platen and the stem 40 pasesdownwardly through an opening in the housing and cx tends through thebore 39 thereof. The head 41 slidably fits the bore 39 and is sccured inplace on the stem by a cross pin 43, the end portions of which projectoppositely'from the head 41 and are received and guided in slots 44formed at the opposite sides of the housing, thereby prevent.- ingrotary movements of the member in its housing. A coiled spring 4.3surrounds the stem 40 within the bore 39 of the housing and is confinedbetween the wall at one end of the bore of the housing and the head -11of the plunger-like member. Any desired number of plunger-like membersmay be employed although as shown in the drawings I prefer to make useof four such members, these being arranged in a straight line lengthwiseof the platen and parallel with the axis thereof and each being movableradially of .the platen. The coiled springs 45 tend to maintain the lipsof the plunger-like members in contact with the platen but the membersare adapted to be pressed outwardly radially of the platen.compressing'the springs 4-5 and forcing the lips 42 away from thesurface of the platen and exposing parts of the stems 40. as indicatedin Fig. 5. The purpose of moving the clamping lips away from the platenand moving the stem; 40 outwardly to :pose their outer ends is toposition the p t ngerlike members for proper coiiperation with the billsheet as will be subsequently explained at greater length.

The preferred means for moving the clamping and stop members relativelyto the A plurality of cam members 46, one for each of said members. arearranged on the axle section 17 and are secured to said section by pins47 so that the nose 48 of each cam member 4i; is adapted to cooperatewith the head 41 of one of the plunger-like members, although the lowercylindrical portion of the cam is always free -fr0m contact with theplunger.

To'the right of the right-hand side bar 8 of the carriage truck a pinion49. is secured to the axle section 17 by a cross pin 50 (Figs. 1 and Theteeth 51 of the pinion 49 mesh with the teeth 51-. of a gear segment 53which segment forms a plate-like arm of a lever. the oth r arm :34 ofwhich is angularly in a handle or finger piece 55 by which the lever maybe controlled by the hand of the operator. The hand-controlled leverjust referred to is provided with a pivot or fulenlargcd portion 37 anda reduced end portion 555 with which the enlarged portion forms ashoulder 59 (Fig. 2). The handcontrolled lever is in the nature of aline spacing lever supplementary to the usual line spacing lever as willbe later fully explained. Said supplementary line spacing lever isperforated to fit over the reduced portion 53 and against the shoulder59 of the fulcrum pin. After the lever is in place on i the reducedportion of the pivot pin the end of the portion 58 is upset or spread asindicated at 60, which operation serves to fix the pivot pin and thelever together. The body portion 56 of the pivot pin is journalcd in acylindrical boss. enlargement or bearing 61 formed integrally with theright-hand end plate 19 of the platen carrier. The lefthand face of theenlargement 57 of the pivot pin abuts against the right-hand face of theboss 61 and the left-hand end portion of the body 56 of the pivot pinprojects beyond the left-hand face of the boss (31 and has fixed to itby a cross pin 62 an arm or stop member 63 (see Figs. 2, :3 8-a.;d 7 theside of which abuts against the left-hand face of the boss 61. Theconstruction is such that While the ivot. pinm'ay turn freely in itshearing it is eld frommoiing: endwise thereof. The stop arm 63 isadapted to coiiperate with a plurality of notches formed in theperiphery of the platen head 13, three notches being shown in thedrawings and numbered for convenience of description 64, 65 and 66 (Fig.7i Each. notch has a short side which may be termed its working side orface and which is substantially radial of the platen and a longer sideat right angles to the short radial side. A wire spring 67 is coiledaround the enlargement 61 (Figs. 1 and 2) and around the part 57 of thepivotv pin, said spring being confined between the supple mentary linespace lever and the rightrhand side bar 19 of the platen carrier. Oneend of the spring is hooked over a pin 68 projecting laterally from theright-hand side bar 19 and the other end is booked. over a shank of aheaded screw (39 projecting inwardly from the lower arm or gear portion53 of the supplementary lever. The spring 67 continues to turn the lowerarm 55, of the lever forwardly and not many maintains a nose or curvedstop portion 53 on the lever in engagement with the tops of the geardisposed. ipclining forward and terminatingcrnm pin comprising a bodyportion 56. an

teeth 51 on the pinion 49. The nose is formed at the lower rear side ofthe platelike arm 5 and contiguous to the gear teeth 52. said nosehavin; its working portion, or that face which is contaetiz-e with thegear teeth 51 curved to conform to the CllClt containing the tops ofsaid gear teeth. The construction is such that the contact face of thenose or stop 53 i adapted to engage the tops ot a plurality of the gearteeth 51 and thcl'elrr to etl'cctivel stop a further movement of thesupplementary line space lever under the force constantly exerted by theSpring GT.

The normal pos tion of the supplementary line space lever is illustratedin Fig. l. and it wi l he understood that the upper arm 54- of saidlever may he pulled forward by the handle 55. causing the gear teeth ofthe segment 5;) or lower arm of said lever to cooperate with the teeth51 ot' the pinion -19 to turn the axle section 17 to which said pinionis se ured. it will he further understood that when the handle .35 isreleased the snpplcmentar v line space lever will he re stored to normalposition automatically by the spring HT and the pinion 19 and the axlesection 17 will he returned or restored to the positions from which the)tartcd. The snpplementm-y line space lever has a constant or unvaryingthrow or movement. this movement heing limited in one direction h thecooperation of the nose 53 with the tops of the pinion teeth 1 and in thopposite direction h the coop ration of the pawl or stop memher 6 withone or another of the notche formed on the peripher v of the platen head1 which last named cooperation will he explained in detail hereafter.The gear segnu-nl is so proportioned that when the stop memher tilt ishrought into cooperation with the platen head 1!) to etl'ect thepositive arrest of the lever. the teeth near the forward end of the gcarsegmcnt 53 will he in mesh with the pinion teeth 51. From what hashecnsaid it will he apparent that the shaft or axle section 17 and the cammembers it on said axle section may he given an unvarving extent offorward and haclnvard rotation under impulses received from thesuppiementary line space lever and its restoring spring (37, and that hreas z= of the gear connection b tween the sup;tit-mentauv line spacelever and the axle section 11' said axle section and the cam memhers it?fixed thereon have a single normal p sition. This normal position of theshaft and cam memhers is illustrated in Fig. 5.

Means are provided for connecting the shat't or axle section IT with theplaten so that the rotary movement communicated to the axle section llin one direction may he transmithrd to the platen. 'lhe connecting m*ans between the platen and the axle section 17 comprises a smallratchet wheel having a collar portion 71 which is fixedly connected withthe axle section 17 by a pin 7'2 (Fig. :2). The ratchet wheel 70 abutsthe inner face of the platen head 13 and as clearly shown in various ofthe 0 rating views said ratchet wheel is provit ed with three ratchetteeth, said teeth being numhered 73, T4- and 75 and each comprising ashort radial working face and a longer curred face connecting theworking face with the working face of an adjacent tooth. Cooptratingwith the teeth of the wheel 70 is a pawl T l. which as shown in Fig. 2is pivoted on a headed shoulder screw 77 which is screwed into theplaten head 13 and projects inwardly therefrom. A depression 78 isformed in the inner face of the platen head 1;) surrounding theshouldered portion of the screw 7? and a corresponding depression T9 isformed oppositely in the pawl 70. The depressions 7S and T9 register andform a housing for a wire spring 80 which surrounds the scl'cW 77 withinthe, housing and has one of its ends fixed to the platen head and itsother end fixed to the pawl. The spring 80 tends to maintain the pawl 76in engagement with one or another of the teeth of the ratchet wheel 70.It will be understood that when the axle section 17 is turned in linespacing direction the ratchet wheel T0 will he turned with it, causingthe short working face of one or another of the teeth of the ratchetwheel to engage with the end portion of the pawl 76 in such a Way as toforce said pawl ahead and to cause a rotary movement of the platen head13 on which said pawl is mounted as well as a corresponding rotarymovement; of the platen. This feature of the invention will he morefull; explained later on; at this place it is only necessary to callattention to the fact that when the handle of the supplementary lever ispulled forward, turning said lever on its fulcrum, the operation servesnot only to communicate rotary movements to the axle section 17 but alsoto cause rotary movement of the platen by reason of the ratchet and pawlconnection 70. 76 between the axle section 17 and'the platen.

Besides the means just: described for communicating rotary movements tothe platen, other and independent platen turning means are provided. Thelatter means comprises the suitahle devices for coiiperating with theplaten and include a rock shaft 81 jonrnaled on the right-hand side bar8 of the carriage truck. said rock shaft at its forward end car- -"lllja line spacing handle 82 and having fixed to its' rear end by a pin 83 acylindrical pruvl-liousiug ht (Fig 1 and 2). The housing is hored out toreceive a plunger-like pav'l carrier comprising a stem 85 and a headhlt. the latter termina ing in a pawl tooth ST. A cross pin 88 passesthrough the the noteheslliZ, 93 and 94 and the teeth 'head 86 andprojects beyond the surface Vlt'CS thus far described, including therocli close together so that the reater part of the thereof, the endportions of the cross pin engaging'in slots 5!) formed lengthwise of thehousing 84. A coiled spring l-O surrounds the stem 85 and serves tonormally maintain the cross pin 85 in contact, with the top of the slots59, as shown in Fig. l and to rnaintain the pawl projected. A coiledrestoring spring 91 serves to maintain the rock shaft 81 and the partsfixed to it in the relations shown in Figs. 1 and 2, said rock shaft.and the parts fixed to its ends composing a 5 line spacing lever. Itwill be noted that the; pawl tooth ST is normally maintained a shortdistance away from the face of the platen head 13.

The line spacing or platen rotating deshat't 51 and the parts carried byit. resemble generally the corresponding parts found on the Smithlreniier machine. In the present I instance the pawl tooth ST is adaptedto 'co operate with crown ratchet teeth formed by notches .12. J3 and 94cut in the face of the platen head 13. The shapes of the notches and theratchet. teeth formed thereby are best shown in Figs. to 13 inclusive.In these figures the dotted lines aand 6 indicate respectively thebeginning and end of thei travel of the pawl tooth 51', the path oftravel of said tooth being in part arcuate and having as its center theaxis of the rock shaft 81.

Thebase of the notch 92 so shaped that 1 when it has been brought toposition to be engaged by the pawl tooth 81' (as shown in Fig.,S) saidbase will be horizontal. Thetop of this notch 92 may be radial as may )ethe base and top of the next succeeding notch 93. The haseof the nextnotch 94, however, is sharply inclined so that the tooth formed betweenthe notches 93 and 94 has one substantially radial and the othersidesliarply inclined thereto, the construction being such that theouter wall of the tooth is much longer than the inner, wall. Forconvenience of description this tooth will be numbered ill" while thetooth preceding will be numbered 9 3. it will be noted that formedbetween them; are comparatively outer fact of the laten head 13 issmooth and in the same p ane as the crowns of the teeth 93 and 9st andthe pawl tooth 87 will not cooperate with the smooth part to effect aturning of the platen. \Vhen, however, the platen has been turned sothat the notches 92, 93 and 9-4 are within the path traveled by the pawltooth 87, it will be apparent that an operation of the line spacinglever 82 1 will cause said pawl tooth to cooperate with one or anotherof the crown ratT het teeth onv the platen head 13 to eltect a turningmove ment of the platen to a greater or less extent.

As has been said my improvements are especially adapted to billing work.The particular embodiment of my invention which has been illustrated anddescribed is especially designed for a form of bill known as an expressway-hill and used by express companies in billing merchandise to becarried. it has not been deemed necessary to illustrate the bill sheetin the, present instance. it being sullicient to say that said billsheet has blau spaces on four dill'erent lines variably spaced apart andwhich are required to be tilled.

Referring now to the mode of operating my improvements in filling in away-bill of the character described, it will be recalled in the firstplace that the axle section 17 and 'the cam members it; normally occupythe positions illustrated in Fig. If the platen and the parts mounted onit. do not happen to occupy the positions shown in this view theoperator may, preliminary to introducin; the first bill into themachine, grasp the left-hand platen finger wheel which is fixed to theaxle section 15 and turn the latter,

causing the platen to rotate in line spacing direction until thecombined clamping and stop members occupy the positions shown in 1 1g.5. During this rotary movement of' the platen the axle section 17 andthe cam members 46 will remain motionless so that the inner ends of theheads 41 of the comhined clamping and stop members will be brought intocontact with the noses 48 of the cam members, the result being that saidcombined members Will be automatically 'forccd outward radially of theplaten until they reach the positions illustrated in Fig. 5. The loweredge portions of the paper table :26 which lie in the paths of the lips42 are cut away indicated at 26 (Fig. 5) in order that the lips may passfreely therethrough and not to obstruct the turning movements of theplaten. The spaces 3t) (Fig. 4) which divide the feed roller arelikewise provided to afford a free passage of be displaced by the lipsand the feed roller will not interfere with the turning movement of theplaten. From an inspection of Fig. 5 it will be noted that. the clampingportion or lip 42 of each clamping and stop member lies when forcedoutward to the limit of-its movement under and close to the paper table26 and form practically a continuation thereof, so that. the way-bill orwork sheet may beintroduced into the machine 'over the paper table andforward of the lips 42 and its leading edge will be di rectec intoengagement with the exposed or working portions of the stems 40 whichperform the functions of stops or gaging means for the leading edge ofthe bill sheet or that edge first wholly introduced into the machine andserve to properly st uare or aline said bill sheet when it is passedownwardly the lips 4:? so that the feed roller will not v cooperatewith the pawl 76 to connect the into contact with said stems 40 bet weenthe lips 42 and the flattened portion 33 of the platen and to as ure theintroduction or entering of the work heets always at the same point orline. After the bill sheet has been properly alinetl the operator maygrasp the handle 35 and pull it forwardly, causing a rotation of thesupplementary line spacing lev r. During .is movement of the lever fromthe dotted line position indicated in Fig. 5 to that indicated in Fig.l, the axle section 17 will he turned. carrying the noses 48 of the cammembers out of ent gagement with the heads t1 and permitting I thesprings 45 to force the combined clamping and stop members inwardly.causing the I lips 49 to engage with the bill sheet at its I leadingedge portion and clamp said bill sheet securely against the platen.During this initial stage of the rotation of the sup- I l g l l l l l lplementary line spacing lever just described. the platen will remainmotionless, the pawl 78 riding over the back of the tooth T4 of theratchet wheel T0. The parts are arranged so that immediately after thelips 42 have been moved inward to operative position the short radialworking face of the ratchet tooth 73 will be brought intocngagemcnt withthe pawl 76. as illustrated in Fig. (5. The result will he that duringthe completion of the rotation of the supplementary line space leverthatis in its movement from the dotted line position of Fig. to the positionindicated in Fig. Tthe ratchet. tooth 73 will axle section 17 with theplaten and the latter will be turned with the axle section from theposition illustrated in Fi t to that of Fig. 7. It will be noted that tiis brings the clamping lips 42 forwardly past the under side or bottomof the platen against which the printing takes place, or past theprinting line, and from an inspection of Fig. 4 it will be understoodthat the clamping lips 42' during their movement from initial positionto that of Fig. 7 pass either between or at one side of the sections 30which cotnpose the main feed roller. The limit of the downward movementof the supplementary spading lever is determined by the engagement ofthe stop member 63 with the short radial side of the notch 64 in theperiphery of the platen head 13 and this engagement of the member 63with the radial side of the notch 64 also limits the turning movementofthe platen and prevents overthrow thereof.- T his will be understoodfrom an inspection of Fi .-7.

fly the full movement of the supplementary lever the bill sheet has beenfed forward into position for receivin the first item or line ofwriting, and said lever may now be released and automatically restoredby its spring to the initial position illustrated in Fig. 5, thisrestoring movement as has been i explained also carrying back the axlesection 17 and the cam members -16 to initial position. During thisreturn movement of the axle section and the cam members the platen willnot he ati'ected. it remaining in the position to which it has beenturned bv the orward movement of the supplementa 1-;- lever. but therelation between the ratchet wheel and the pawl 76 will be altered. thepawl riding over the backs of the teeth 74 and T5. The first line oritem may be written by operatin the printing instrumentalitics in theusual way. and then the carriage may be retracted and the platenadvanced or line spaced for receiving the second line of writing, byoperating the iisual line space handle 8:2. The result of this operationwill he explained in connection with Figs. 8 to 11 inclusive. Figs. 8and 9 correspond with Fig. 7, these two first mentioned figures showingthe platen in the same position as docs'l ig. 7 but omitting variousdetails shown in Fig. 7 and illustrating more clearly the crown ratchetteeth on the platen head 13. Referring first then to Figs. 8 and 9 itwill be seen that when the platen is positioned for writing the firstline of the bill the base of the notch 92 in the platen head is inposition to he engaged by the pawl tooth 8? when the regular line spacehandle 82 s operated. When. therefore, this bandle is o erated after thecompletion of the first line, the pawl tooth 87 is forced inwardly anddownwardly against the base of the notch 92, causing a turning movementof the platen from the. position shown in Figs. 7, S and 9 to that shownin Figs. 19 and 11, thus advancing the bill sheet into position toreceive the second line of writing. it will he noted that during the oeration of the handle 82, the platen wil be turned directly and notthrough its connection with the axle section 17, as was the case withthe first turning movement in the cycle of operations now beingdescribed. The second line having been written the platen may be rotatedfrom the position illustrated in Figs. 10 and 11 to that illustrated inFigs. 12 and 13 by again operating the handle 82. As the handle isturned the pawl tooth 87 will be forced inwardly against the face of theplaten head 13 and will come into contact with the upper outer corner ofthe tooth 94, as will be. understood from an inspection-of Figs. 10 and11. Because of the special and peculiar shape of this tooth the pawltooth 87 will be prevented from engaging the notch 94, althou h thegreater part of the base of this notch hes in the path of the pawltooth, as indicated in Fig. 10. Being prevented from enga ing with thenotch 94 the pawl tooth will be forced to ride down over the face of thetooth 94: until said pawl tooth drops into the notch 93 and engages withthe tooth 93,

as shown in Fig. 11.

The turning movement of the platen justdescribed is a :lii'ei-t one and been written, the platen may be turnedand the bill sheet advaneerl for receiving the fourth line of .writingiy again operating the line space handle 52. causing the pawl tooth 87to enter the notch Sit and engage the tooth 94, and so turn the platenfrom the positions shown in Figs. 12 and 13 to thatshown in Fig. 14.This movement of the platen will also be considerably less than thefirsttwo line spacing movements effected by the handle 82, so that the extentof angnlar movement transmitted to the platen at the last two describedactuations of the bandle is considerably less than the sum of twosuccessive movements of the pawl 87 between the lines a and b. Theway-bill, as has been stated, is in the present case a four line one sothat when the fourth line has been filled in the bill is completed andthe next operation is to feed it out of the machine and automaticallynnclamp itso that it may be withdrawn and a new bill sheet inserted. Bythe various direct rotary movements communicated to the platen thro ighthe line spacing handle 82- the platen has been turned, carrying thepawl 76 to the position shown in Fig. 14. During these direct turningmovements of the platen the axle section 17 and the wheel thereon willremain motionless the pawl 78 riding over the backs of the teeth of theralehet wheel. At this stage then the relation between the pawl 76 andthe ratchet wheel 70 will he that shown in Fig 14, the )awl being in.engagement with the bark o the ratchet tooth 73.

In order to feed the bill sheet out of the inaehiue and uni-lamp it, thesupplementary line sparing lever is operated with the re sult that theaxle seetion l7 and the ratchet \VlitLl T0 are turned inde eudentlv ofthe platen until the rah-bet tooth T5 is brought into contact with thepawl To. after which the pawl will be forced ahead HlHll'llC platenturned .llllll the movement of the suppleinentarv line space lever iseoinpleied. The result will be thatthe platen will be turned from theposition shown in Fig. l t to that shown iii Fig. 15. From an lllSPt't.

Further however, leased it will be restored to normal position with thatshown in Fig. 5, but that the 1 elamping lips- 4; in Fig. 15 areoperative.

while in Fig. 5 the are inoperative. This diil'i-ri-u e is due ie thefact that iii Fig. 15

tbesap diueutary line spacing lever is ll(i.\'ll in depressed positionand the axle 1 section 17 and ram members to are consequently shown inabnormal position. Vhen,

the siipplenientaiw' lever is reas hown in Fig. 5 by its spring (SIwithout all'i-cting the platen and at the same time the axle seeti n ITand the tram members 46 1 is not communicated through the axle sec tton17., The third line of writing having will be turned backward to normalposition. During the backward turning move ment of the cam members thenoses 48 there on will contact with the heads 4.1 of the clamping andstop members andwill force said last named members radially oiitwarfl Ito the position shown in Fig. 5, thereby releasing the bill sheet sothat it may be with drawn. afterwliieh a new bill sheetmay be inserted.advanred and written upon in the manner explained. It will be noted thatduring the last described opening of the elauiping lips 412 the platenwas motionless. the clamping lips being moved away from the platen bythe turning movement of the cam members ll; under the impulse of thespring 67.

From what has b en said it will be seen that the operation ofintrodiieing. squaring and damping a bill sheet and then advaneing itline by line for filling in blanks thereon, and then for turtheradvancing 1t and unelanipmg it may be rapidly elfected and comprises fora four liu: bill sheet, first a depression of the supplementarv linespacmg lever, then three operations of the i'egiilar line spat-emechanism and tin-ally a second depression of the supplementary linespace lever, which last operation not only feeds the bill out andniiclanips it but positions the platen and the squaring and claim ingmeans for rccei *ing a fresh bill. f eoiirse. it will be apparent thatfor a bill sheet having a greater or less amount of writing to be tilledin the construction and arrangement of some of the parts wouldnecessarily be altered and the operations above outlined would be variedto a greater or less extent. Any necessary changes in eonstrui-tion andoperation for'auy particular style of bill may, however, be readiljw t ll l l l 5 T! invention in this way the first steps correspond with thosealready described in con nection with Figs. 5 to 7 inclusive. When theplaten has been turned to the first line position, as shown in Fig. 7,the supplementary line space lever is released, returning to normalposition and carrying with it the axle section 17 and the cam members 46back to normal position. The parts will then be in the positionsillustrated in Fig. 16. From a consideration of this figure itwill benoted that the pawl 76 is in contact with the back of the tooth 75.After the first line has been written the automatic line spacing leveris again depressed, causing a rotation of the ratchet wheel 70 andbringing the working face of the tooth 74 into cooperation with the pawl76. cousin; a turning movement of the platen from the position shown inFig. 16 to that shown in Fig. 17. The platen will be arrested in theposition shown in the latter figure by the cooperation of the stopmember :3 with the notch (35 in the periphery of the platen head 13, andthe bill sheet will be advanced into position for receiving the secondline of writing. When the supplementary line space lever is releasedfrom the position shown in Fig. 17 it will return to normal position inthe usual way and the axle section 17 and the ratchet wheel will beturned back to normal position. During this backward taming movement thepawl 76 will ride over the ratchet tooth T5 and will be forced by itsspring down on the back of the ratchet tooth T4 in advance of the short.working face of the ratchet tooth 75. When the second line has beenwritten and the supplementary lever is again operated the ratchet wheel70 will be turned, turning the working face of the tooth 7:? intoengagement with the pawl 76 and forcing the latter ahead, therebycausing the platen to turn until it reaches the position shown in Fig.15 here it will be arrested by the cooperation of the stop (33 with thenotch G6 in the platen head.

It will be understood that by operating my invention in the way lastdescribed, a two line bill sheet may be properly entered, clamped,advanced step-by-step and then fed forwardly out of the machine andunclampcd.

It will be seen that by my invention 'I provide a stop and a clamp or aplurality or set of stops and clamps which in the present case aremounted on the platen and are movable radially thereof; that thepinrality of clamping and stop members are independently movable, sothat if one of them encounters an inequality in the work sheet or isobstructed in any way the eti'cctive operation of the other members isnot interfered with or impeded as would be the case were said membersnot independently mounted; that the actuating means: for moving thestops and clamps comprise cam members which are mounted'on a shaft oraxle section rotatable relatively to and independently of the platen,said shaft or axle section having a single normal position; that in thepresent case a member or members each combining'the functions of a stopand clamp are employed; and that the actuating devices or cam members:may be caused to cooperate with the combined clamping and stop membersin either of two ways. in ore of which ways the actuating devices or cammembers remain nmtionless and as the platen is turned the clamping andstop members are caused to engage with the motionless cam members andare automatically forced outward thereby during the rotation of theplaten, and in the other of which ways the platen and the clamping andstop members remain motionless while the shaft or axle section is turnedto bring the cam members thereon into cooperation with the motionlessclamping and stop members.

Any suitable means for performing the function of a side guide or agefor the work sheet or bill may be emp oyed in connection with the novelend stops and clamps. In Figs. 1 and 2, for example, a side guide 9-5 ofwire is shown secured to the end bar or plate 19 of the platen frame bya screw 96 in position to cooperate with the righthaud side edge of theWork sheet when itis introduccd into the machine. The side guide 95 erse is not claimed herein by me.

I; will be understood that although'the stops and clamps for the leadingedge of the work sheet are shown combined, yet iffor any reason it isdesired to separate them, stop members separate from the clampingmembers may be provlded.

Various other changes may be effected,

within the scope of the invention and parts of it may be made use ofwhile at. the same time other parts are dispensed with.
